Abstract: Proposed is an apparatus for the spray treatment of printed circuit boards. It has conveyor means for conveying the printed circuit boards (2) with a horizontally oriented PCB surface plane. Provided above the plane of conveyance (7) is a nozzle device (16) for spraying the top surface (13) of the printed circuit boards (2) with a liquid treatment medium. The apparatus is equipped with a suction device (26) that permits the sprayed-on treatment medium to be suctioned off from the top surface (13) of the printed circuit boards (2) during the spray process. In this manner the treatment medium is prevented from backing up, and a high-quality treatment process is ensured.
